Novel green bio-composite geopolymeric thermo-plasters for innovative building applications: upcycling spent coffee ground
2022
This study proposes the reuse of spent coffee ground and biomass fly ash in the development of green geopolymeric thermo-plastering for innovative building applications. The former waste is the major residue of the brewing process, that is usually used as fertilisers or disposed of in landfill with extreme harmfulness for the natural environment. The latter is an industrial waste generated during the Kraft paper-pulp process, that is usually landfilled. The mortar is produced with a combination of metakaolin (30 wt.%) and biomass fly ash (70 wt.%), and natural siliceous sand filled with spent coffee ground (up to 17.5 wt.%). The high amount of reused waste makes the material an optimum cand…
Interactive Tools for the Preservation, Dissemination and Study of Silk Heritage—An Introduction to the SILKNOW Project
2018
Silk was a major factor for progress in Europe, mostly along the Western Silk Road’s network of production and market centers. The silk trade also allowed for the exchange of ideas and innovations, having impacts at economic, technical, functional, cultural and symbolic levels. However, silk has today become a seriously endangered heritage. Although many European specialized museums are devoted to its preservation, they usually lack the size and resources to take advantage of state-of-the-art digital technologies. The aim of this paper is twofold; firstly, we introduce SILKNOW, an interdisciplinary project that has been recently funded by the H2020 Programme of the European Union in order t…
"Elämä on Feodalismia ja säätyjen sääteilyä" ‒ Historian oppiaineen tekstimaailma virtuaalitodellisuudessa
2017
Tässä tutkielmassa tarkastelen historian oppiaineen tekstimaailmaa virtuaalitodellisuudessa. Aihe on ajankohtainen ja tärkeä, sillä virtuaalitodellisuuden hyödyntäminen kouluopetuksessa on todella uusi ilmiö, eikä virtuaalimaailman tiedonalakohtaisia tekstejä ole tutkittu aiemmin. Virtuaalitodellisuus antaa mahdollisuuksia oppilaiden aktiiviselle osallistamiselle ja tiedon kriittiselle tulkinnalle, joten se palvelee myös uuden opetussuunnitelman tavoitteita. Tutkimuskysymykseni ovat: 1. Millaisia tekstilajeja opiskelijat ovat käyttäneet virtuaalitodellisuudessa? 2. Millaisia multimodaalisia keinoja opiskelijat hyödyntävät teksteissään? 3. Mikä funktio multimodaalisilla keinoilla on? Lähesty…

"Bitcoin" kā alternatīvā valūta
2018
Mūsdienās virtuālās valūtas, it īpaši “Bitcoin”, kļūst par aizvien aktuālāko tematu, tāpēc autore izvēlējās to pētīt. Bakalaura darbā “”Bitcoin” kā alternatīvā valūta” tika pētīta virtuālā valūta: tās raksturojums, veidi, un virtuālās valūtas “Bitcoin” iespējas kļūt par alternatīvo valūtu. Darba mērķis ir izanalizēt “Bitcoin” valūtu, tās priekšrocības un trūkumus kā alternatīvas valūtas. Lai to sasniegtu, tika izvirzīti vairāki uzdevumi: •izpētīt dažādus informācijas avotus par virtuālo valūtu un konkrēti par “Bitcoin” valūtu; •raksturot virtuālās valūtas veidus; •izanalizēt tiesisko regulējumu virtuālo valūtu jomā; •izanalizēt “Bitcoin” norēķinu sistēmu; •izanalizēt pieejamos statistikas d…
Virtual Reality for Collaborative Learning in Teacher Education
2022
This poster discusses the potential of virtual reality (VR) for collaborative learning. VR can provide engaging, social and creative digital environments for collaborative knowledge construction but its pedagogically meaningful uses and affordances are only just developing. We present the design of a case study where pre-service teachers become acquainted with the pedagogical potential of VR through collaborative exploration and subsequently collaboratively design and reflect on authentic school projects using VR. nonPeerReviewed

Avaluació de l’efectivitat d’un programa d’intervenció basat en marxa virtual i exercici terapèutic en la funció motora, el to i el dolor de persones…
2023
Estudis previs han mostrat el potencial de les teràpies basades en l’activació del sistema de neurones mirall, concretament les teràpies de marxa virtual (MV) en persones amb afectació del sistema nerviós central (SNC). Malgrat això, aquestes teràpies no han estat estudiades com a potenciador de l’exercici terapèutic (ET) utilitzat com a rehabilitació usual sobre persones amb LM incompleta. La hipòtesi principal de la present tesi és que l’aplicació de la teràpia de MV combinada amb un programa d’ET produeix la millora de la funcionalitat, la disminució del dolor neuropàtic i la millora del to muscular en persones amb LM incompleta. Per tal de validar aquesta hipòtesi, l'objectiu de l’estud…
Efficient remote authentication
2013
In 2003, Kennel and Jamieson described a method of remote machine authentication. By authentication, the authors meant that the remote machine is non-virtual, and the operating system on the remote machine is not malicious. The described method does not consider the variety of versions of each operating system. The description completely ignores the existence of modules that can be plugged into the operating system. The authors of this paper adapt the method described by Kennel and Jamieson to the real world so that itcan be applied without prior knowledge of theoperating system or the modules on the remote machine. peerReviewed
Skeleton-Based Multiview Reconstruction
2016
International audience; The advantage of skeleton-based 3D reconstruction is to completely generate a single 3D object from well chosen views. Having numerous views is necessary for a reliable reconstruction but projections of skeletons lead to different topologies. We reconstruct 3D objects with curved medial axis (whose topology is a tree) from the perspective skeletons on an arbitrary number of calibrated acquisitions. The main contribution is to estimate the 3D skeleton, from multiple images: its topology is chosen as the closest to those of the perspective skeletons on the set of images, which means that the number of topology changes to map the 3D skeleton topology to topologies on im…
